High standards, refined, zero defects, high standards, refined, zero defects, is the basic requirements of enterprises for employees, but also the basic working attitude of employees. High standards are prerequisites, refinement is the basic requirement, and zero defects are the ultimate goal. The three are interlocking and indispensable.

[Abstract]:
Thermally conductive adhesives are widely used in LEDs, microprocessors, memory modules, cache memories, sealed integrated chips, DC/DC converters

Thermally conductive adhesives are widely used in LEDs, microprocessors, memory modules, cache memories, sealed integrated chips, DC/DC converters, IGBTs and other power modules, power semiconductors, solid state relays, and bridge rectifiers.

The thermal paste has a certain adhesion and will not dry out. It can be attached to a higher temperature device in the power supply or power device to transfer heat away. One of the typical applications is in the application of drive power in LED bulbs. In the export of LED lights, in order to pass the UL certification, manufacturers often use two-component potting glue for potting. The lamps exported to the United States require a 50,000-hour warranty. The quality of the LED lamp bead is no problem at present. The main fault is the power supply. The power supply after potting with potting glue cannot be disassembled. The lamp is discarded for replacement. If the power supply is partially filled with the thermal conductivity mud, the heat can be effectively exported, and if the power supply has a problem, the power supply can be easily replaced to save the cost for the enterprise. Of course for lamps that require waterproofing. Because the thermal conductive mud can not fill all the gaps like the potting glue, it can not be waterproof and moisture-proof, and still need to use potting glue.

Another typical application is in the LED fluorescent tube. For the design of the power supply at both ends, in order not to occupy the size of the lamp too much, the space of the two power supplies is relatively small, and the power of the 1.2 m LED fluorescent lamp is usually designed. 18w to 20w, so the heat generated by the drive power becomes larger. The thermal fluid can be filled into the gap of the power supply, especially attached to the power device to help heat dissipation and extend the life of the lamp. For some sealed module power supplies, it can be partially filled with thermal mud to achieve thermal conductivity.

Dongguan Dongyan Electronics is mainly engaged in nano-carbon copper foil tape aluminum foil tape, conductive adhesive, conductive cloth tape, thermal tape, PET double-sided tape, PI high temperature resistant glue, etc., only to satisfy customers.
